My screen resolution was properly detected, as were my network and wireless interfaces, but no networks showing up in KNetworkManager. A quick check confirmed that in fact neither the broadcom-sta driver nor the brcm80211 firmware were installed. So my hardware is recognized as claimed, but not supported.

I have a broadcom driver so I want to sus this out before install. As I don't have a hard wired connection i need to download any requirements before install.

Should you need to prefetch firmware .debs, to put on a usb-key to transfer the files to another computer, you can download them as either a zip or tar.gz file from http://cdimage.debian.org/cdimage/unoff ... d/current/ and extract it to a folder called firmware, you should see a number of .deb files.

If you have a laptop with a Broadcom 43xx chipset. this Ubuntu wiki article is a good guide to getting it going if you can download the needed packages to a USB stick from an Internet-connected computer and then plug it into the laptop after you install Kanotix.
